Subject: [PATCH] feat: wire executors to use parametersOverride for fallback
 models

Updates runOnce in all four generation executors to accept an optional
parametersOverride argument. When running the fallback model, the
executor uses fallbackParameters from node data instead of the primary
model's parameters.
